Vagueness, Uncertainty and Granularity
in Spatial Information
The standard RCC calculus is a logic of crisp regions, i.e. those
with well defined boundaries. However, in many applications, particularly
within Geographical Information Systems, boundaries may not be well defined,
or at least may not be precisely known. Tony Cohn and Nick Gotts have developed
an extension of the RCC logic applicable to such vague regions.
Investigating how to deal in a principled way with spatial information affected by vagueness, uncertainty and granularity was the subject of an EPSRC research project undertaken jointly by the
GIS research group at Keele University and the Leeds QSR group:
Managing Vagueness, Uncertainty and Granularity in spatial information systems (EPSRC grant GR/M56807), and awarded an "outstanding" evaluation for its final report.
